Question

hi do the following
1. In Search programs and files (Windows 7) area, type in regedit, and press Enter.
2. If prompted click yes,
3.  expand the following HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
4. click the sid that related to your admin profile (if you not sure, click each sid and in turn look to the right hand side of registry editor it will show who that sid is related to one of the registry files should hae in description localhost\admin or
something similair)
5. right click the sid and press delete.
6. restart your machine and log back on with the admin account, this will then rebuild the admin profile... dont worry when it loads and none of your personal settings are saved or files or folders... go to c:\users
in here you will see two folders for the admin account, one will be just admin and the other most likely admin.localhost
i cant remember which one is which but just check both, one will still have all your files and folders in it.
i suggest making a backup of your data before doing this incase something does go wrong, but ive had this happen many times in a domain enviorment and has worked for me everytime.
